Beverly Sills, 75, is stepping down as chairman of the Metropolitan Opera, citing family reasons. “She said that her tenure would indeed be the last act of a 60-year career in the arts world that wended its way through the roles of soprano star, opera manager, Lincoln Center overseer, fund-raiser and, finally, Met chairwoman in 2002 – a volunteer job for which she had left a previous retirement. ‘I am stepping down for good. I had already decided that I was not really serving any of the masters well’.”
